Application filed "August 19, 1324. Serial No. 732,359.

To all whom it may concern Be it kn wn that 1, JOHN M. MYERS, a citizen of the United States, resident of Scottsville of Kentucky, have made a certain new and useful Invention in Fell-Drilling Machines;

and I declare the to be a run, clear, exact description of the same,

seen as will enableothers skilled in the art to" which i tappertains to make and use the:

invention, referenee'being'had to the acconr panyingdrawings, and to letters or figures ofrefe'rence marked thereon; which form a part of this specification. i l

' The invention has relationto well drilling machines, having for an objectto provide improved machine of simple and durable nature. i

invention consists in the novel construction and'combination of parts, as hereaifter set f r h- In the accompanying drawings illustrating the invention, Figure l is a side view of the invention with parts broken away; Figure 2 is a plan view of the invention; Figure 8 is a section on the line 33, Figure 2, and Figure 41 is a front view of the invention.

In these drawings the numeral 1 designates a wheeled support including front and rear bolsters2 and 3, whereon is mounted the well drill frame consisting of a rectangular base 4, rear standards 5 having an upper cross bar connection 6, and inclined brace bars 7, a central rear post 8, being hinged to the upper cross bar at 9, and having a removable bolt connection 10 with the lower cross bar of the framing and at its upper end carrying upper and lower pulleys 11 and 12.

The power shaft of the machine is indieated at 13, and is provided with a belt wheel 14, loosely mounted thereon and having an inner circular track 15, with which a friction disk 16 upon a shaft 17 has driving engagement.

A horizontal drum 18 is loosely mounted on the power shaft 13, and is provided at one side with a large spur gear 19 fast thereto and forming an end flange thereof, and at the other side with a brake wheel 20 forming an end flange thereof, a hand lever- 21 being adapted to tighten and to loosen the brake band 22 upon said brake wheel, to thereby hold the drum 18 stationary, should occasion arise. The friction in the county of Allen and State drive aforesaid retates the drum 18 to wind up t e dril r p foll win e ent e th ll hr gh use f v av th ro atiee sf said rum e g accompl sh by P nwe 3 fas upo heit l7, a d pimee l aise slide e a d e ng adjust ble th eeeb h s A lever 24 into with said geei l Qe I l$ Qt hei with and in e :e ute with a dr m 2. ,leo ely m unt 'sl n the S ei a l and having a one sideae 1 membe 26, the I co p mentary shite member wh r o is ca r e by a d p nien A shaft 27 is mounted intermedia e he height or the standard 5 abo e and invest o drum nd is Pmv ded with. a guide pulley 28,, loosely moun ed ther on, said shaft :having fast thereto] forwardly and upwardly projecting converging arms-29,

carrying at the free end thereof a guide pulley 30 overlying thecliium rope drum 18, said arms and the pulley Q f fi ifid th reby being rocked or vibrated up and down by crankv 31 fast upon the power. Sha 13 and having a roller 32 working in cam track 33 of rocker arm 34:, the upper end of which is fast to the aforesaid shaft 27, said rocker arm projecting forwardly and downwardly from its shaft 27 at about right angles to said arms 29.

In the working of the connecting rod 34, a helical spring 35 one end of which is fast to the framing and the other end of which is fast to shaft 27, is tightened or wound as the rocker pulley 30 is moved upward to let out slack in the drill rope or cable 37 wound upon the drum 18 and passing first around said guide pulley 28, thence in the opposite direction around said rocker pulley, and thence in the opposite direction upwardly over the pulley 12 at the top of the post 8, said rope then passing downwardly and carrying at its lower end the drill (not shown). As the rocker pulley is moved downwardly the helical spring in its unwinding will assist in the raising of the drill.

The rope or cable 36 is wound upon the drum 25 and passes upwardly therefrom over the pulley 11 at the upper end of the post 8, and at its lower end carries the easing or bailer (not shown) the latter being let down into the well as it is drilled by force of gravity and the rotation of said drum, following which the hand lever 24: is operated to make the connection between pinion 23 and the drum, winding up the cable 36. A hand lever 38 operates slidable clutch member 39 upon the power shaft 13 into and out of clutch engagement with the complementary member upon the hub of the power or belt wheel 14:.

The auxiliary shaft 17 is pivotedaat one" end thereof at 40 and is movable pivotally through operation of ahandlever 41 to dissaidshaft and carrying the guide pulley overlying said drum and the guide pulley 28 upon said shaft, and the rocker arm'iil projecting forwardly and downwardly from said shaft at about right angles to said arms 29, the Weight of the arms 29 and of the rocker arm 8 l'will, owing to the drill rope bend passing around pulleys 28 and 30, hold the drill rope taut in the return" or upward movement of the drill.

Owing to the friction wheel 16 on shaft 17 being driven by contact with the inner circumferential surface of the belt wheel 14 it is possible to bring the two drums 18 and 25 more nearly together, so that there may be a gearing connection 19, 23 therebetween,

and the entire machine is rendered more compact, leaving room on the same supporting frame 7 for the engine driving the machine.

In a well drilling machine, a power shaft having a belt wheel provided with an inner circumferential track, an auxiliary shaft provided with a. friction wheel bearing against said track, a drill rope'drum loose upon said power shaft and carrying a spur gear wheel, a'casing rope drum loose upon said auxiliary shaft, a pinion fast upon said auxiliary shaftand having a clutch connection 'with said casing rope drum and being slidable to releasesaid clutch and mesh with said spur gear wheel, said auxiliarynshaft being pivoted at one end and movable to disengage 'said frictionv wheel from said track, and a rock shaft carrying a'drill rope guide pulley and fast upwardly and for wardly projecting armsprovided at their free ends with a drill rope guide pulley overlying said drill rope drum and a fast downwardly and .forwardly projecting rocker arm, said powershaft having a crank engaging said rocker arm.

In testlmony whereof I affix my signature. JOHN M. MYERS
